Benefits of technology
The invention is an optical element driving module that includes a fixed portion, a movable portion, a driving assembly, and at least a glue. The fixed portion includes a housing and a base, while the movable portion is movable relative to the fixed portion. The driving assembly includes at least a coil and at least a magnetic element for driving the movable portion to move relative to the fixed portion. Specifically, the housing, the base, and the magnetic element are adhered to each other by the glue. The technical effects of the invention are to provide a reliable and efficient optical element driving module that is easy to assemble and disassemble for maintenance.
Problems solved by technology
However, a large number of glue application stations are often required because a large number of components need to be assembled, thus leading to increase of assembly time and production cost.
Additionally, because the components inside a camera module have small dimensions, it is difficult to rapidly and precisely apply glue in the correct positions between the components by manual labor.
Therefore, conventional camera modules usually have problems with low production yield and high production costs.

An optical element driving mechanism is provided, including a base, a holder movably coupled to the base for holding an optical element, a casing, a frame, a driving assembly, and an adhering member. The casing has a top wall and a plurality of side walls extending from the edge of the top wall along an optical axis of the optical element, and the top wall is closer to a light-incident end than the base. The frame is disposed on the top wall and has a frame protrusion extending toward the base. The driving assembly is configured to drive the holder to move relative to the base, and an accommodating space is formed between the base, the frame and the casing. The adhering member is disposed in the accommodating space and configured to directly adhere to the base, the frame, the casing, and the driving assembly.
Description
CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority of U.S. Provisional Patent Application Ser. No. 62 / 688,694, filed on Jun. 22, 2018, U.S. Provisional Patent Application Ser. No. 62 / 711,036, filed on Jul. 27, 2018, the entirety of which are incorporated by reference herein.BACKGROUND OF THE INVENTIONField of the Invention[0002]The application relates in general to a driving module, and in particular, to a driving module which is used to hold and move an optical element.Description of the Related Art[0003]As technology has advanced, a lot of electronic devices (for example, tablet computers and smartphones) have incorporated the functionality of taking photographs and recording video. These electronic devices have become more commonplace, and have been developed to be more convenient and thin. More and more options are provided for users to choose from.[0004]Since the space inside the camera module is limited, the components are usually adhered to each oth...
